Subject: Cards Class

Hi, I'm an utter newbie to Ruby (and OOP!) and I thought I'd share my
very first project. It's nothing special - just a simple class that
simulates a deck of cards, but I'd like to get your comments to see if
there's anything I can do better (enjoy!):

class Deck
  @@Cards =
['Two','Three','Four','Five','Six','Seven','Eight','Nine','Ten','Jack','Queen','King','Ace']
  @@Suits = ['Spades','Hearts','Diamonds','Clubs']

  def  initialize
    @top_card = -1
    @deck = []
    52.times do |card|
      @deck << card
    end
  end

  def draw
    @top_card = @top_card + 1
    if @top_card < 52
      @deck[@top_card]
    else
      raise 'There are only 52 cards in a deck!'
    end
  end

  def shuffle
    @top_card = -1
    @deck = @deck.sort_by {rand}
  end

  def suit
    @@Suits[@top_card/13]
  end

  def face
   factor = @top_card/13
   index = @top_card - 13*factor
   @@Cards[index]
  end

  def set_card(card)
    @top_card=card
  end

end
